VELP Scientifica has designed convenience into the NDA 701 Dumas Nitrogen Analyzer to let the user concentrate on evaluating the results that are produced in just 3 to 4 minutes per sample.
Once up to 4 discs (30 positions each) have been loaded, press the start button and walk away.

With the best limit of detection on the market and an RSD lower than 0.5% for EDTA, the user is assured of high precision results.

NDA 701, the ideal solution for high throughput, being fully automated and able to run 24/7.

The Dumas method starts with a combustion to burn the sample, obtaining elemental compounds. Water is removed by a first physical trap (DriStep™), positioned after the combustion, and a second chemical one. Between the two, the elemental substances passed through a reduction furnace. The auto-regenerative CO2 adsorbers let pass only the elemental nitrogen that is detected by the LoGas™ innovative Thermal Conductivity Detector (TCD) with no requirement for a reference gas.
